- Box quantity of 100: Supplied in bulk packaging, reducing per-unit cost and ensuring sufficient stock for high-volume or repeat fastening tasks.
- Gray color designation: Provides visual identification for quick sorting and inventory management on the job site.
Applications
- Mechanical assemblies subject to continuous vibration where fastener retention is critical.
- Structural connections requiring a secondary locking feature integrated directly into the nut.
- General hardware and construction applications using standard 3/8 coarse-thread bolt patterns.
- High-volume fastening projects where bulk packaging improves workflow efficiency.
